Description 13
P64H2 I/O Hub
The primary role of the P64H2 is to provide an integrated I/O bridge to the 64-bit PCI-X segments.
This subsystem supports two independent 64-bit PCI-X segments, each with two 64-bit/100MHz
PCI-X slots. The Adaptec AIC-7901 embedded controller is enabled via one of the PCI-X
segments of the P64H2.
ICH3 I/O Controller Hub
The primary role of the ICH3 is to provide the gateway to all PC-compatible I/O devices and
features. The SE7501BR2 uses the following ICH3 features:
• 32-bit/33 MHz PCI bus interface
• Low Pin Count (LPC) bus interface
• IDE interface, with Ultra DMA 100 capability
• Universal Serial Bus (USB) interface
• PC-compatible timer/counter and DMA controllers
• APIC and 8259 interrupt controller
• Power management
• General purpose I/O
• System RTC
Super I/O
The National Semiconductor†PC87417 Super I/O Plug-and-Play Compatible with
ACPI-Compliant Controller/Extender is used on the SE7501BR2 server board. This device
provides the system with:
• Two serial ports
• One parallel port
• Floppy disk controller (FDC)
• PS/2†-compatible keyboard and mouse controller
• Wake event control
Serial Ports
One DB9 connector is provided on the back panel for the Serial A port. The Serial A port is
compatible with 16550A and 16450 modes. This port can be set to one of four different
COM ports, each of which can be enabled separately. When enabled, each port can be programmed
to generate edge- or level-sensitive interrupts. When disabled, the serial port interrupts are
available for add-in cards.
A DH10 10-pin serial header is available on the baseboard for an optional Serial B port. The
Serial B port can be used as an Emergency Management Port.
Parallel Port
The SE7501BR2 baseboard provides a 25-pin parallel port back panel connector. The Super I/O
provides an IEEE 1284-compliant 25-pin bi-directional parallel port. BIOS programming of the
Super I/O registers enables the parallel port and determines the port address and interrupt. When
disabled, the interrupt is available to add-in cards.

14 Intel Server Board SE7501BR2 Product Guide
Floppy Disk Connector
The floppy disk connector on the server board provides the interface to the floppy disk drive from
the floppy disk controller.
Keyboard and Mouse Connectors
The separate keyboard and mouse connectors, found on the back panel of the server board, are
PS/2-compatible. The keyboard and mouse connectors are interchangeable.
Processor(s)
The Intel®Server Board SE7501BR2 accommodates one or two Intel Xeon processors with 512KB
L2 Cache via two SKT604 604-pin zero-insertion force (ZIF) sockets. The processors interface
with the system bus at 533 MHz, backwards compatible with 400 MHz. When only one processor
is installed, it should be in the socket labeled CPU1 and the other socket must be empty.
For a complete list of supported processors, see:
http://support.intel.com/support/motherboards/server/SE7501BR2
Dual Processor Operation
The Intel Xeon processor interface is dual-processor (DP)-ready. The processor subsystem
includes a single VR (Voltage Regulator) to support both processors. Interrupt generation and
notification for the processors is done by the Advanced Programmable Interrupt Controllers
(APICs) in the ICH3 and P64H2. When two processors are installed, both processors must be of
identical revision, core voltage, and bus/core speeds.
Boxed Processor Fan Heat Sink
Complete thermal solution including a processor wind tunnel (PWT), fan, and heatsink is supplied
with each boxed Intel Xeon processor.
✏ NOTE
Do not install the Processor Wind Tunnel when using the Intel®Server Chassis
SC5200 with hot swap redundant power. To install the heat sink you must use
the Retention Mechanisms supplied with the SC5200 chassis. For this chassis,
see the installation instructions beginning on page 47.
Otherwise, install the processor wind tunnels according to the instructions
provided in this document or in the SE7501BR2 Quick Start User’s Guide. These
instructions are different than those included with the boxed processor. For
proper processor cooling, the fan inlet air temperature should be below 45 °C.
CAUTION
Clearance is required at each end of the fan heat sink to ensure unimpeded
airflow for proper cooling. Restricting the airflow through the processor heat
sink can cause overheating and subsequent failure of the processor.

Description 15
Memory
The Intel®Server Board SE7501BR2 contains four 184-pin DIMM sockets and provides support
for up to 8 GB of DDR266 memory. The memory subsystem provides dual memory bus
architecture; the memory on the board is partitioned into two banks of DDR DIMMs. DIMMs must
be installed in pairs, providing a 144-bit wide data path via two separate memory buses.
The server board supports up to four ECC DDR DIMMs that are compliant with the JEDEC
DDR266 specification. A wide range of DIMM sizes are supported, including:
• 128 MB
• 256 MB
• 512 MB
• 1 GB
• 2 GB
The minimum supported memory configuration is 256 MB, using two 128 MB DIMMs. The
maximum configurable memory size is 8 GB using four 2 GB DIMMs.
✏ NOTE
DIMMs must be installed in pairs and must be populated by bank starting
with DIMM 1A and 1B (contiguous sockets). Although the SE7501BR2
server board architecture allows the user to mix various sizes of DIMMs
between banks, DIMMs must be identical within the banks. For a list of
tested memory, see:
http://support.intel.com/support/motherboards/server/SE7501BR2
PCI I/O Subsystem
The SE7501BR2 server board provides three PCI bus segments:
• Segment C with two PCI-X 64-bit / 100 MHz slots (Slot 1 and 2)3
• Segment B with two PCI-X 64-bit / 100 MHz slots (Slot 3 and 4)4
• Segment A with two PCI 32-bit / 33 MHz slots (Slot 5 and 6)
The following table outlines the capabilities of each 64-bit bus segment. The least capable card
installed on that bus determines the bus mode/speed. In other words, the bus will run at the speed
of the slowest installed card.
Table 2. 64-bit PCI Segment Configuration
# of slots populated per segment Segment B (mode, speed) Segment C (mode, speed)
0 PCI-X, 100 MHz PCI-X, 133 MHz
1 PCI-X, 100 MHz PCI-X, 133 MHz
2 PCI-X, 100 MHz PCI-X, 100 MHz
3This segment will operate at 133 MHz when only one slot is populated.
4Modular RAID on Motherboard (M-ROMB) support is provided via Slot 4.

16 Intel Server Board SE7501BR2 Product Guide
Segment C: 64-bit / 100 MHz PCI-X Capable Subsystem
The 64-bit/100 MHz PCI-X segment includes:
• Two 3.3 V keyed full-length, full height PCI expansion slots that can support PCI-X add in
cards up to 133 MHz (PCI-X Slots1 and 2). These slots are backward compatible to 64-bit/100
MHz, 64-bit/66 MHz, 64-bit/33 MHz, and universal keyed 32-bit/33 MHz PCI cards.
The PCI-X features include:
• Bus speed up to 133 MHz
• 3.3 V signaling environment
• Burst transfers up to a peak of 1000 Megabytes per second (MB/s)
• 8-, 16-, 32-, or 64- bit data transfers
• Plug-and-Play ready
• Parity enabled
✏ NOTES
Speed on the PCI-X will be programmed by the BIOS according to loading on the
segment. When a segment is configured with a single PCI-X 64/133 card the bus
will work at 133 MHz; with two PCI-X 64/133 cards the bus will work at 100
MHz.
If you install a slower card into one of the PCI-X 64/100 connectors, the bus speed
for both connectors will be lowered to the speed of the slowest adapter.
Segment B: 64-bit / 100 MHz PCI-X Capable Subsystem
The 64-bit/100 MHz PCI-X segment includes the following embedded device and connectors:
• Two 3.3 V keyed full-length, full height PCI expansion slots that can support PCI-X add in
cards running at 100 MHz (PCI-X Slots 3 and 4). These slots are backward compatible to 64-
bit/66 MHz, 64-bit/33 MHz and universal keyed 32-bit/33 MHz PCI cards.
• Integrated Adaptec AIC-7901 U320 Single Channel SCSI Controller
The PCI-X features include:
• Bus speed up to 100 MHz
• 3.3 V signaling environment
• Burst transfers up to a peak of 800 Megabytes per second (MB/s)
• 8-, 16-, 32-, or 64-bit data transfers
• Plug-and-Play ready

Network Interface Controllers (NICs)
The Intel®Server Board SE7501BR2 includes one 10/100Base-TX network connection, based on
the Intel 82550PM Fast Ethernet Controller (NIC1)5, and one 10/100/1000Base-TX network
connection, based on Intel 82540EM Gigabit Ethernet Controller (NIC2). Facing the rear of the
system, the gigabit controller is on the left, next to the video connector.
You can disable the embedded NICs in BIOS Setup Utility. When disabled, the controller(s) are
not visible to the operating system.
✏ NOTE
To ensure EMC (Electromagnetic Compatibility) product regulation
compliance, the system must be used with a shielded LAN cable.

NIC Connector and Status LEDs
The Intel®Server Board SE7501BR2 supports two RJ45 connectors, one for the 10/100-Megabit
Fast Ethernet controller (NIC1), and the other for the Gigabit Ethernet controller (NIC2).
NIC1 drives two LEDs on its RJ45 connector. These LEDs indicate link/activity on the LAN and
the speed of operation. This connector is on the right side when looking at the I/O area at the back
of the board. The green LED to the right of the connector indicates a network connection is in
place when it is on and transmit/receive activity when it is blinking. The green LED to the left of
the connector indicates 10 Mbps operation when it is off and100 Mbps operation when it is lit and.
See the following table for an overview.

NIC2 drives two LEDs located on its RJ45 connector; this connector is on left side when looking at
the I/O area in the back of the board. The green LED to the right of the connector indicates a
network connection is in place when it is on, and transmit/receive activity when it is blinking. The
bi-color LED to the left of the connector indicates 10-Mbps when it is off, 100-Mbps operation
when it is green, and 1000-Mbps operation when it is yellow. See the following table for an
overview.

ACPI
By using Advanced Configuration and Power Interface (ACPI), an ACPI-aware operating system
can place the system into a state in which the hard drives spin-down, the system fans stop, and all
processing is halted. In this state the power supply is still on and the processors still dissipate some
power, so the power supply fan and processor fans are still running.
✏ NOTE
ACPI requires an operating system that supports this feature.
The server board supports sleep states S0, S1, S4, and S5. When the server board is operating in
ACPI mode, the operating system retains control of the system and the OS policy determines the
entry methods and wake-up sources for each sleep state – sleep entry and wake-up event
capabilities are provided by the hardware but are enabled by the operating system.
• S0: Normal running state.
• S1: DC Power remains on. The operating system saves the context and enters a low-power
state. The system can wake from the S1 state using a PS/2 keyboard, mouse, or USB device,
by pressing the power button press, or from a wakeup event.
• S4: Hibernate or Save to Disk. The memory and machine state are saved to disk. Pressing the
power button or another wakeup event restores the system state from the disk and resumes
normal operation. This assumes that no hardware changes were made to the system while it
was off.
• S5: Soft off. Only the RTC section of the chip set is running in this state.
CAUTION
The system is off only when the AC power is disconnected.
Wakeup Events
The SE7501BR2 system supports several wakeup events.
Wake on LAN
Wake on LAN allows system power to be activated through the network. If the system is in the S1
or S4 state, it can be turned on remotely by sending a specific packet to the remote system. The
system contains a configuration option that allows the on-board NICs to be enabled to wake the
system from a S4 or S5 sleep state, even if the operating system disabled Wake on LAN when it
powered down the system. This provides an option for users who want to use standard, but
non-secure, Wake on LAN capability for operations such as after-hours maintenance. Server
management features provide a secure system power-up, plus the ability to provide BIOS boot
option.
